Color correction is a crucial step in video production. Primary corrections set the overall look, adjusting exposure and color balance for the entire image. Secondary corrections target specific areas, allowing for creative enhancements and fine-tuning.
Understanding the difference between primary and secondary color correction is key to efficient workflows. Mastering tools like scopes, HSL qualifiers , and masks enables precise adjustments. A systematic approach ensures consistency and quality across your entire project.

Primary color correction applies global adjustments affecting the entire image (exposure, contrast, color balance)
Secondary color correction targets specific areas or color ranges within the image
Primary corrections establish a baseline for the overall look of the footage
Secondary corrections refine and enhance specific elements after primary adjustments
Perform primary color correction first, followed by secondary adjustments
Different tools and controls used for primary vs secondary corrections in most video editing software
Primary correction aims for neutral, balanced images
Secondary correction enables creative enhancements and stylistic choices
Efficient color grading workflow requires understanding the distinction between these techniques
Basic Color Correction Techniques
Exposure and Contrast Adjustment
Manipulate overall image brightness using lift , gamma , and gain controls
Adjust contrast by manipulating difference between darkest and lightest parts (curves, levels, contrast sliders)
Use waveform monitor to evaluate and adjust exposure levels across the image
RGB parade provides detailed view of individual red, green, and blue color channels for precise adjustments
White Balance and Color Balance
Neutralize color casts by adjusting temperature and tint for accurate color representation
Utilize vectorscope to assess and correct color balance by visualizing color distribution
Proper use of scopes and histograms crucial for accurate and consistent color corrections across shots and scenes
Isolating Colors for Adjustment
HSL Qualifiers and Color Keys
Use HSL (Hue , Saturation , Luminance ) qualifiers to isolate specific color ranges
Apply color keys to isolate and adjust colors based on hue, saturation, and luminance values
Enhance or suppress specific elements (skin tones, sky color, product highlights)
Understanding relationship between color spaces (RGB, HSL, LAB ) crucial for effective secondary color correction
Masks and Tracking
Create power windows or masks to isolate specific areas of the frame
Apply tracking and keyframing for corrections on moving objects or changing scenes
Use blending modes and opacity controls to integrate secondary corrections seamlessly
Implement geometric shapes for targeted corrections within the frame
Systematic Color Correction Approach
Standardized Workflow
Begin with primary corrections followed by secondary adjustments for consistency across shots and scenes
Implement color management system using LUTs (Look-Up Tables) to maintain color accuracy throughout post-production
Develop and utilize custom presets or looks for consistent styles across projects or within productions
Create shot-matching process to ensure continuity between camera angles and lighting conditions
Organization and Quality Control
Organize and label color correction nodes or layers for clear and efficient workflow
Establish quality control process including regular monitor calibration
Review corrections on multiple display devices for consistency
Develop collaboration strategy with directors, cinematographers, and clients to translate creative vision into grading decisions
